Continuous and Discrete Time Signals

My senior who is in NIT, suggested me Neso Academy and I told her I already subscribed to the channel. Most of the times, I've written tests right after watching your videos (even finals), thank you for the clear explanation.

[@chandranibose2286]

Another question is while explaining the discrete part Sir took reference of the graph drawn in the CTS part and have plotted t0,t1....,tn and said that the continuous signal is defined for every value of (t) then again he said we can't find the difference between t1 and t0 as it is not defined at every point of (t) PLEASE CLEAR MY DOUBT ITS A REQUEST TO ANYONE WHO UNDERSTOOD THIS PART.

[@digitalmarketing5782]

Doubt: in last 10:21. If let's say x[0]=1, how can you tell it's 1 of 3rd in series {1,0,1,2,2,2} it can be 1st one know? If it's 1st one the data is wrong again!

Sir here you have explained that 'dc is not a signal' but at example you told about system where we are using a pump as system and ac as signal. my question is if we use dc pump as system can we consider dc as signal then?

[@bibhudebnath7527]

sir, your information is very informative, simple & easy to understand.

[@gabemvp]

In the last example I think you may also add the step in which the DTS is plotted, which is the T value. Refreshing things up here, took these classes a long time ago. Clear and great explanation! Thanks

[@gabemvp]

Actually for a more general view, it would not be necessary, just if more specifics are needed... Let's see, I will run through all the playlist :)

[@prudviraj8623]

ex:dts=[1,0,1,2,2,1],from left to right sir you tell that second 1 as a x[n] at n=o.But also can take first and last 1 as a x[n] at n=0.why you only take second 1 as a x[n] at n=0?

[@annurao6232]

I have the same query

[@nawsheenmuzamil3174]

Sir, you talked about DC not being a signal, can you elaborate please? And what about step function, will it also be not categorised as a signal beyond t0?

[@deepaksree6]

unit step is a signal because it changes from o to 1 at t=0(discontinuous at zero). but a dc is never changing ,it is always constant for all time t

[@ashutoshkumar3045]

It's deserve 10m subscriber as much as❤️❤️

[@preethikasaran6536]

Hello Sir, You have explained how n is an integer for uniformly sampled signal then how is n an integer for non uniformly sampled signal. Please clarify it.

[@yagnatherapybydromtrivedi971]

Sir, Can you elaborate existence of n? having doubt in that like how you calculate T to 1 and 2T to 2 likewise. Kindly explain that!

[@aditisarkhel3484]

sir i have a doubt, in the last example of discrete signal , if suppose signal is not given to us how did we got to know that x[n] at n=0 will be 1?

[@vvdpabhishek3464]

U r a fool if they mention it in the ques then automatically u can generate the signal common sense dude

[@anju754]

@Prathipati tejopavan There will be an arrow to the value at n=0 in the given signal x[n].

[@-ManishaBanu]

Sir can you please explain the effect of P, PI, PID, controllers on rise time, peak time, max. Peak overshoot, settling time in a comparative way? Please sir

[@manojkarajada7188]

9:55 u said we simply put an arrow at where amp is 1 we take it as n=0 but y u choose middle 1 insted u take first 1 as n=0 ,i am so confused plz answer me

[@ahmadarfeen2554]

Manoj Karajada we have 2 samples at right of n=0 so we can't put n=0 for 1st sample as we will always right the sample values in order of increasing n.

[@varey1556]

Hello sir ! please explain between x[n] and x{n}. thanks after that

[@gustavoadolfosilvaquibano6350]

Thank you for the video, one more thing, if I ask you a question you will answer?

[@TanishqIsHere]

*What if 0 is not in the domain of the discrete time function? Where to put the arrow?*

[@ganasampathmaradana3854]

I too have same doubt. Did you get answer?

[@prachiargulewar2409]

I too have same doubt

[@dashrathkumar4534]

when you will start at that time time must be zero.so n corresponding to that time always keep a value 0.

[@Fourier-x3k]

There are two kinds of single depending on the value they take wrt to time So their names are continuous time signal CTS and discrete time variable TTS One which take values for every value of time is CTS other which takes value for discrete values of time TTS CTS representated as x(t) t is independent variable time and x is dependent variable that is signal TTS is represented as x(n) X is signal and n is integer For example the diff in the two consecutive times is T in two consecutive times is 2T in this way we represent it for 1t,2t,3t as for 1,2,3 factor of T is hidden And for representing purpose in TTS, we place arrow below the value TTS takes for integer 0 that is when time was 0 the value it took Thank you #feymanTechnique

Sir how can we say that signal have integer inputs in non-uniform sampled signals?

[@hussamalanesi7432]

Very clear and informative, thanks sir.

[@dilushawijayasooriya4685]

Why do we have to remove T? And how did you just remove T like that? Is it by equating T to 1? Can we cancel an independent variable whenever we want to? I don’t understand

[@nehalsamala11]

Since T is on both the axes, it gets cancelled. its like taking common and cancelling

Hey Neso Academy, Do you have a Lecture on Discrete-Time Fourier Transform(DTFT)?

Can you give me the real world analogy for elementary signals

[@dhananjaysingh5677]

Sir how did you know at n is equal to 0 the amplitude is 1 ?? In discrete signal case

[@abhijitbanik3861]

is mechanical force variation with respect to time is a signal and whether fft and other techniques are applicable to them

[@TapToTech]

You just say that in continuous time signal in every time t there will be value on y axis,,and again u are saying in time slab 4:02 that between t1 and t2 y is not confirmed,,,so what is the main thing

[@vasanthakumar1991]

What will be X axis if non-uniform sampling is performed to get a Discrete signal??

good explanation sir..plz upload all the videos of signals and systems.

Why should we use [. ] Brackets in discrete time signals sir ?

Sir could u tell me how to convert continuous time function to discrete time function. Actually i need to know how to convert a differential equation in time domain to difference equation in discrete form

[@Messiah60fps]

very much thanks

[@ayushikhaparde2086]

When u told that,'when n=0,x{n} is 1then why didn't you have chosen the first most value of 1when x(-2)...I mean how did u get to know that we have to chose middle 1 rather than choosing first or last 1

[@varchasvjohari717]

Sir, in example of discrete time signal the value of n=0 you saw from graph i.e. 1 so what about if no graph is given and only if x{n}= {1,0,1,2,2,1} is given then how would you find n=0 ?

[@chandranibose2286]

I have same question please clarify

[@chandranibose2286]

Another question is while explaining the discrete part Sir took reference of the graph drawn in the CTS part and have plotted t0,t1....,tn and said that the continuous signal is defined for every value of (t) then again he said we can't find the difference between t1 and t0 as it is not defined at every point of (t) PLEASE CLEAR MY DOUBT ITS A REQUEST TO ANYONE WHO UNDERSTOOD THIS PART.

sir! how did you cancel out T??????? Plz clear my doubt 7:16

[@surajbhatt2050]

sir why we are putting arrow on the 1 which is in the middle there are two 1 also leftmost and rightmost why we are not putting arrow on that 1's?

[@AhamedKabeer-wn1jb]

Good explained

[@ravipratihast]

sir,some confusion occurs? how you canceled T out from x[nT]??

[@jyotidixit7581]

Ravi Pratihast He has taken time period of sampling, T=1, i.e. The signal is sampled for every delta_t=1, thus the values are plotted for every nT=nx1=n. That is why he has omitted T in the description.

[@ravipratihast]

So, n is then taken as 0, 1,2, 3...n?

[@jyotidixit7581]

Ravi Pratihast Yes, in this case, therefore, n being a discrete variable has taken the values like 1,2,3...n and x(n) has been mapped for those values.
